Is ozone injection more effective than using an airstone?
Yes, the Black Max ozone jet or injector is much more efficient, as the ozone is forced into the water under a vacuum, rather than just bubbled through it. This creates a greater number of smaller bubbles, with more surface area for the ozone to interact with the water. This also aids in circulating the water within the tank. With an airstone, the bubbles tend to be larger and travel straight up and out of the water.
